Definitions
- the invention relates to genetically generated soluble Fusion proteins consisting of non-immunoglobulin families associated human proteins or parts thereof and various Share the constant region of immunoglobulin molecules.
- the functional properties of both fusion partners surprisingly remain in the fusion protein.
- EP-A 0325 262 and EP-A 0314 317 are corresponding Fusion proteins consisting of different Domains of the CD4 membrane protein of human T cells and known from human IgG1 fractions. Some of these fusion proteins bind to the glycoprotein with the same affinity gp120 of the human immunodeficiency virus like the cell-bound CD4 molecule.
- the CD4 molecule belongs to the immunoglobulin family and is therefore very great in terms of its tertiary structure constructed similarly to immunoglobulin molecules. this is also valid for the ⁇ chain of the T cell antigen receptor, for those Mergers have also been described (Gascoigne et al., Proc. Natl. Acad. Sci. USA, Vol. 84 (1987), 2937-2940). Because of the very similar domain structure, was therefore in In this case, the maintenance of the biological activity of the both fusion partners can be expected in the fusion protein.
- immunoglobulin coupled human Proteins do not belong to the immunoglobulin family and are assigned to the following classes: (i) membrane-bound proteins, the whole or part of their extracellular domain Fusion is introduced.
- these are thromboplastin and cytokine and growth factor receptors like that cellular receptors for interleukin-4, interleukin-7, Tumor necrosis factor, GM-CSF, G-CSF, erythropoietin;
- non-membrane-soluble proteins that are whole or partially incorporated into the merger.
- proteins of therapeutic interest such as. Erythropoietin and other cytokines and growth factors.
- the fusion proteins can be in known pro- and eukaryotic Expression systems are manufactured, but preferably in mammalian cells (e.g. CHO, COS, BHK cells).
- mammalian cells e.g. CHO, COS, BHK cells.
- the fusion proteins according to the invention are based on of their immunoglobulin content using affinity chromatography easy to clean and have improved pharmacokinetic properties in vivo.
- the Fc part in the fusion protein is for the use in therapy and diagnostics quite advantageous and leads e.g. to improved pharmacokinetic Properties (EP-A 0232 262). Then again the possibility of removal for some applications of the Fc portion desirable after the fusion protein expressed in the advantageous manner described, has been detected and cleaned. Then this is the Case when the Fc portion is for use in therapy and diagnostics prove to be a hindrance, e.g. if that Fusion protein serve as an antigen for immunizations should.
- Papain or Pepsin are used, for example, for the production of F (ab) fragments from immunoglobulins used (Immunology, ed. Roitt, I. et al., Gower Medical Publishing, London (1989)), however, they do not split particularly specific.
- the blood coagulation factor Xa recognizes the relatively rare in a protein Tetrapeptide sequence Ile-Glu-Gly-Arg and performs one hydrolytic cleavage of the protein after the arginine residue by cleavage sequences that the described tetrapeptide were first included by Nagai and Thogersen in one Hybrid protein introduced by genetic engineering (Nagai, K.
- the invention thus relates to genetically engineered soluble fusion proteins consisting of non-immunoglobulin family belonging to human proteins or parts of it and different proportions of constant regions of heavy or light chains of immunoglobulins different subclasses (IgG, IgM, IgA, IgE).
- the constant part of immunoglobulin is preferred heavy chain of human IgG, particularly preferred of human IgG1, the fusion to the hinge area he follows.
- the Fc part by a built-in factor Xa cleavable cleavage sequence can be easily separated.
- the invention further relates to methods for genetic engineering Production of these fusion proteins and their Use for diagnostics and therapy.
- Blood clotting is a central process in the human organism. It is regulated accordingly Coagulation cascade, in which a variety of cellular factors and plasma proteins interact. The entirety of this Proteins (and their cofactors) are called clotting factors designated.
- the end products of the coagulation cascade are thrombin, which induces platelet aggregation, and fibrin, which stabilizes the platelet thrombus.
- throombin catalyzes the formation of fibrin from fibrinogen and will itself formed by limited proteolysis of prothrombin.
- factor X factor Xa
- factor Xa responsible in the presence of factor Va and Calcium ions bind to platelet membranes and prothrombin splits.
- thromboplastin becomes in the extrinsic "pathway" (Tissue Factor) synthesized by injured cells and activates factor X, along with factor VIIa and Calcium ions. It used to be assumed that the Thromboplastin activity limited to this reaction. However, the thromboplastin / VIIa complex intervenes at the level of factor IX also activating in the intrinsic "pathway". So there is a thromboplastin / VIIa complex one of the most important physiological activators of the Blood clotting.
- Thromboplastin is an integral membrane protein that is not belongs to the immunoglobulin family. Thromboplastin cDNA sequences are published by a total of four groups (Fisher et al., Thromb. Res., Vol. 48 (1987), 89-99; Morrisey et al. 1987 Cell 50: 129-135; Scarpati et al., Biochemistry, Vol. 26 (1987), 5234-5238; Spicer et al., Proc. Natl. Acad. Sci. USA, Vol.
- Thromboplastin cDNA includes an open reading frame that encodes a polypeptide of 295 amino acid residues, of which the N-terminal 32 amino acids act as a signal peptide.
- Mature thromboplastin consists of 263 amino acid residues and has a three-domain structure: i) amino terminals extracellular domain (219 amino acid residues); ii) transmembrane region (23 amino acid residues); iii) cytoplasmic Domain (carboxy terminus; 21 amino acid residues). In the extracellular domain there are three potential sites for N-glycosylation (Asn-X-Thr). Is thromboplastin usually glycosylated, but glycosylation appears not essential for the activity of the protein (Paborsky et al., Biochemistry, Vol. 28 (1989), 8072-8077).
- Thromboplastin is used as an additive to plasma samples in coagulation diagnostics needed.
- prothrombin coagulation time determination e.g. quick test
- the Thromboplastin required for diagnosis is currently being developed obtained from human tissue using the manufacturing process is difficult to standardize, the yield is low lies and considerable amounts of human raw material (Placentas) must be provided.
- Plucentas human raw material
- the thromboplastin fusion proteins according to the invention are from mammalian cells (e.g. CHO, BHK, COS cells) into Culture medium discharged via affinity chromatography protein A-Sepharose and surprisingly possess high activity in the one-step prothrombin coagulation time determination.
- mammalian cells e.g. CHO, BHK, COS cells
- the plasmid pCD4E gamma 1 (EP 0 325 262 A2; deposited with ATCC under number 67610) is used to express a Fusion protein from human CD4 receptor and human IgG1.

With the enzyme HindIII may only partial cleavage to be carried out here only for one of the two contained in pCD4E gamma 1 Cut HindIII sites (position 2198). Then it lies an open vector, in which a eukaryotic Transcription regulation sequence (promoter) from the open HindIII site is followed.
- promoter eukaryotic Transcription regulation sequence
- the BamHI position is open at the beginning of the coding regions for one Pentapeptide linkers, followed by the hinge and the CH2 and Human IgG1 CH3 domains.
- the reading frame in the BamHI recognition sequence GGATCC is such that GAT as Aspartic acid is translated.
- DNA amplification with thermostable DNA polymerase enables a given Change sequence so that at one or both ends any sequences can be added.
- Oligonucleotides Two oligonucleotides were synthesized using sequences in the 5'-untranslated region (A: 5 'GATCGATTAAGCTTCGGAACCCGCTCGATCTCGCCGCC 3') or coding region (B: 5 'GCATATCTGGATCCCCGTAGAATATTTCTCTGAATTCCCC 3') the Can hybridize thromboplastin cDNA. Oligonucleotide A is partially homologous to the coding sequence Stranges, oligonucleotide B is partially homologous to non-coding strand; see Fig. 3.
- the Desired fragment was obtained and after treatment with HindIII and BamHI in those described above with HindIII (partially) / BamHI cut vector pCD4E gamma 1 ligated.
- the resulting plasmid was named pTF1Fc (Fig. 4).
- pTF1Fc The fusion protein encoded by the plasmid pTF1Fc is in the hereinafter referred to as pTF1Fc.
- pTF1Fc became transient in COS cells expressed.
- COS cells were used with the help of DEAE-dextran transfected with pTF1Fc (EP A 0325 262).
- Indirect immunofluorescence tests showed approximately 25% as Proportion of transfected cells. 24 hours after transfection the cells are transferred to serum-free medium. This cell supernatant was harvested after another three days.
- the first 9 fractions were immediately neutralized with 0.1 ml of 2M Tris buffer pH 8.6 combined and the protein contained by three cycles of concentration / dilution in the Amicon microconcentrator (Centricon 30) in TNE buffer (50mM Tris buffer pH 7.4, 50mM NaCl, 1mM EDTA).
- the so obtained pTF1Fc is electrophoretically pure in the SDS-PAGE (U.K. Lambli, Nature 227 (1970) 680-685). In absence from In SDS-PAGE, reducing agents behave like a Dimer (approx. 165 KDa).
- TF1Fc fusion protein is in low concentrations (> 50 ng / ml) in the one-step prothrombin clotting time determination (Vinazzer, H. Coagulation Physiology and Methods in the blood coagulation laboratory (1979), Fisher Verlag, Stuttgart) active.
- the clotting times achieved are comparable to the clotting times that with thromboplastin that human placenta was isolated.
- Interleukin-4 is synthesized by T cells and was originally referred to as B cell growth factor because it can stimulate B cell proliferation. It practices one Variety of effects on these cells. In particular is this stimulates the synthesis of molecules of the immunoglobulin subclasses IgG1 and IgE in activated B cells (Coffmann et al., Immunol. Rev., Vol. 102 (1988) 5). About that IL-4 also regulates proliferation and differentiation of T cells and other haematopoietic cells. It thus contributes to the regulation of allergic and others immunological reactions. IL-4 binds with high Affinity for a specific receptor.
- the cDNA for encoding the human IL-4 receptor was isolated (Idzerda et al., J.Exp.Med. Vol. 171 (1990) 861-873. From the analysis the amino acid sequence derived from the cDNA sequence shows that the IL-4 receptor consists of a total of 825 amino acids exists, the N-terminal 25 amino acids as Signal peptide act. Mature human IL-4 receptor exists from 800 amino acids and, like thromboplastin, has one Three domain structure: i) amino terminal extracellular domain (207 amino acids); ii) transmembrane region (24 amino acids) and iii) cytoplasmic domain (569 amino acids).
- IL-4 receptor Homologies to the human Il-6 receptor, to the ⁇ subunit of human IL-2 receptor, for mouse erythropoietin receptor and to the rat prolactin receptor (Idzerda et al., op. cit.). It thus, like thromboplastin, is not a member of the immunoglobulin family, but is together with the listed homologous proteins to the new family of hematopoietin receptors expected. Members of this family are 4 Cysteine residues and one located near the transmembrane region conserved sequence (Trp-Ser-X-Trp-Ser) common in the extracellular domain.
- IL-4 / IL-4 receptor system Due to the described function of the IL-4 / IL-4 receptor system is a therapeutic use of a recombinant Form of the IL-4 receptor for the suppression of IL-4-mediated Immune reactions (e.g. transplant rejection reaction, Autoimmune diseases, allergic reactions) possible.
- IL-4-mediated Immune reactions e.g. transplant rejection reaction, Autoimmune diseases, allergic reactions
- the IL-4 receptor fusion proteins are derived from mammalian cells (e.g. CHO, BHK, COS cells) discharged into the culture medium, via Affinity Chromatography on Protein A Sepharose cleaned and surprisingly possess identical functional properties as the extracellular Domain of the intact membrane-bound IL-4 receptor molecule.
